After one week with an iphone my biggest complaint is batterydrain. I barely managed to get through the day…
So I started looking for solutions.
I use activesync and I found a way to double the time or even more :
I changed the activesync from push to fetch
Go to settings – Email,Contacts,… – New Data : disable Push and change Fetch to every hour or manual (I choose every hour)
You can even go to advanced and put them there all on Fetch
At 15:00 hours I now even have 75 % battery left
